I had my ecu reflashed a couple of weeks back and on my service receipt it says they performed the update "TSB EG2004" but from reading from the various posts on this problem the correct flash should be TSB EG2003. I pulled both pdfs from the Toyota tech info site and both claim to fix the same thing but the difference would be EG2004 is for 2002 models and EG2003 is for the 2001 models. Are they the same??? Both TSIBs are attached below..
